套筒灌漿料與普通灌漿料有什么區別？

 瀏覽次數：2166    |      2017-09-21


套筒灌漿料是以水泥為基本材料，配以細骨料，以及混凝土外加劑和其他材料組成的干混料，加水攪拌后具有良好的流動性、早強、高強、微膨脹等性能，填充于套筒和帶肋鋼筋間隙內的干粉料，簡稱“套筒灌漿料”。


其性能相比水泥基灌漿料有區別， 初始流動度要不小于300mm半小時不小于260mm，抗壓強度要求比水泥基灌漿料要高出不少，1天要求達35兆帕，3天要達到60兆帕，28天要達到85兆帕。


套筒灌漿料與普通灌漿的技術執行標準及技術參數不一樣：


普通水泥灌漿料一般執行標準是：【GB/T50448-2015水泥基灌漿材料應用技術規范】


套筒灌漿料的執行標準是：【JC/T408-2013鋼筋連接用套筒灌漿料】
